Ques:- What is cascade loop and how it work and why it used insteadof PID single loop?In cascade, Which loop is faster and slower?
Right Answer:
A cascade loop is a control system that uses two controllers: a primary (master) controller and a secondary (slave) controller. The primary controller sets the setpoint for the secondary controller, allowing for more precise control of a process. It is used instead of a single PID loop when the process has a fast dynamic response that needs tighter control, as it can reduce the effect of disturbances and improve stability.

In a cascade loop, the secondary (slave) loop is faster because it responds to changes more quickly, while the primary (master) loop is slower as it manages the overall process setpoint.
